1 Sure-Flex Plus 4-Way flexing action absorbs all types of shock, vibration and misalignment Torsional Sure-Flex Plus coupling sleeves have an exceptional ability to absorb torsional shock and dampen torsional vibrations. The EPDM and Neoprene sleeves wind up approxi mately 21 torsionally at their rated torque. Hytrel sleeves wind up approximately 7. Angular The unique design of the Sure-Flex Plus coupling s teeth allows for the absorption of angular misalignment without wear. Refer to page 17 for misalignment limits. Angular alignment can be achieved using only a scale and calipers.

The lateral flexibility of the coupling sleeve minimizes radial bearing loads normally asso ciated with parallel misalignment. This feature also allows for easier installation by the use of components bored for slip fits without fretting corrosion occurring at the shaft. Refer to page 17 for parallel misalignment limits. Only a straight-edge and feeler gage are required for parallel alignment. Metric Version Catalog For Imperial information see Catalog P-1690-TBW Axial Sure-Flex Plus couplings may be used in applications with limited axial shaft movements. The axial compressibility of the EPDM and Neoprene sleeves allows for shaft end-float without the absolute transfer of thrust loads.

Determine Service Factor using and Driver Standard AC Motor DC Shunt Motor Load Symbol *Engine, 8 or more cylinders High Torque AC Motor DC Series & Comp. *Engine, 4-6 cylinders L Light M Medium H Heavy *Engine, 3 cylinders or less Turbine * On applications involving varying torque loads, design around the maximum load. Then determine the resulting service factor at minimum load. If this value is greater than 5.2 for EPDM or Neoprene sleeves, or 4.0 for Hytrel sleeves, special coupling alignment will be required (see page 17). Caution: s involving reciprocating engines and reciprocating driven devices are subject to rotational vibrational critical speeds which may destroy the coupling. Consult factory. 6 P-1957-TBW-A4 5/18

5 3. Determine using Coupling Rating Tables Use the following formula to calculate the required coupling kilowatt 100 RPM. 100 RPM = KW x Service Factor x 100 / coupling RPM Use the chart below to find a coupling with a 100 RPM rating which is greater than calculated above. Example: For 4 55 RPM, 1.25 Service Factor: 100 = 4 x 1.25 x 100 / 55 = 9.09 Use #12 EPDM or Neoprene, or #10 Hytrel. Note: Do not exceed a 5.2 Service Factor for EPDM or Neoprene sleeves, or 4.0 for Hytrel sleeves.
